Subject: Create /dev/disk/by-id/wwn-0x... symlinks
X-Git-Tag: 174~706
X-Git-Url: https://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?p=elogind.git;a=commitdiff_plain;h=28c7463999c64517ddce0b52e89161d77dfac373

Create /dev/disk/by-id/wwn-0x... symlinks

Now that both ata_id and scsi_id exports the World Wide Name in the
ID_WWN property, use this to create persistent symlinks. Example

 /dev/disk/by-id/wwn-0x500000e01b83f360 -> ../../sdn
 /dev/disk/by-id/wwn-0x500000e01b83f440 -> ../../sdm
